How to: Make lower items in RelativeLayout respond to gestures

How can I make layouts/views that have a lower z-index in a RelativeLayout response to any gesture, even if the view/layout above them covers the entire screen?

Android - The data is under/inside the toolbar

I have a little problem with my android design code, the data overlaps the toolbar:
I'm just using the navigation drawer with REST Api data adapter result. The data are represented by row.xml:

You put your listview in wrong position.You should put it in content_main.

Why this textfield and appbar overlap?

How can I resolve this problem? Here is the screen:
This is my xml fragment :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

android:layout_height="match_parent"
android:layout_below="#+id/tue_stanze"

I use a navigation drawer for first time and I need to create fragment to use for menu.
tnks for help.
EDIT:
This is my content_main xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.bfco.bocci.androhouse.MainActivity"
tools:showIn="#layout/app_bar_main">
EDIT2: I use this "app_bar_main.xml" that include content_main:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email" />
And this is my main.xml :
<?xml version="1.0" encoding="utf-8"?>
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
</FrameLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />

It's a bit unclear as to exactly what container your fragment is contained in, but somewhere along the way, you should include this attribute
android:paddingTop="?attr/actionBarSize"
OR
android:layout_marginTop="?attr/actionBarSize"
in the appropriate container. Based on what I see above, you could simply add it to the root of your fragment posted above:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="?attr/actionBarSize"
tools:context=".Utenti.Profilo.ProfiloFragment">
Ideally you'd handle it at a higher level, but this should suffice for your example.

How to make a search box not scrolling over scrollview Android

In my home screen I want to add the search box with navigation drawer but I am not able to set the non scrollable edittext over scrollview.
Here is my Code

I want a edittext with navigation drawer which should be sticky and do not scroll with rest of the layout. How can I achive it.
What I want is explained in screenshot below:

Try my below code:

android:layout_height="match_parent">

android:layout_width="match_parent"
android:layout_height="wrap_content">

/>
</android.support.v4.widget.DrawerLayout>
Here Only thing which I have changed is kept the editText outside the scrollView.

Why don't you try to put it out outside the ScrollView. Then just overlay it with a RelativeLayout and the gravity set to top. I can't run it now but in xml should look like something like this
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_centerHorizontal="true"
android:numColumns="2"
android:paddingLeft="#dimen/_4sdp"
android:paddingRight="#dimen/_4sdp"
android:layout_marginTop="#dimen/_220sdp"
android:verticalSpacing="8dp"/>
</RelativeLayout>
</ScrollView>
<!-- Here we add the layout outside the ScrollView -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="#dimen/_200sdp"
android:gravity="top"> <!-- GRAVITY ADJUST -->
<EditText
android:layout_width="#dimen/_280sdp"
android:layout_centerHorizontal="true"

</android.support.v4.widget.DrawerLayout>
Hopefully, it runs smoothly and turns out helpful.

How to place navigation drawers header below statusbar?

I want my header of my Navigation drawer to be below the statusbar. When searching for solutions, every result is about how to place it under the status bar. I have of course tried to "reverse" theese solutions to place the header below. But it hasn't worked and I'm testing it on a Samsung Galaxy S7 API 23
Right now it looks like this:
This is my layout containing DrawerLayout, NavigationView:
<?xml version="1.0" encoding="utf-8"?>

Much of this is auto generated by Android Studio after I created my NavigationDrawer Class from the wizard

You have not put your xml fully so I don't know whats wrong with your xml but if you want your navigation drawer below action bar then put your drawerlayout below your toolbar as follows
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!--Start of the Toolbar and its items -->
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center" />
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"></LinearLayout>
<!--Used for displaying Navigation Drawer slide-->
<LinearLayout
android:id="#+id/navigation_drawer"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:orientation="vertical">
<FrameLayout
android:id="#+id/navigation_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
According to your edited question drawerlayout xml would be like
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

I used the xml file below to achieve what you asked. But this way, the drawer opens below both the "status bar" and the "toolbar"
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent"
tools:context=".MainActivity">
<include xmlns:android="http://schemas.android.com/apk/res/android" layout="#layout/toolbar" />
<android.support.v4.widget.DrawerLayout
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:elevation="5dp">
<FrameLayout
android:id = "#+id/frameLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
</FrameLayout>
<ListView
android:background="#ffffff"
android:id = "#+id/drawerList"
android:layout_width="240dp"
android:layout_height="match_parent"
